Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a cosmetic packaging tube. Background Technology

[0002] Traditional push-to-pop packaging tubes typically pop out the bottom product when pressed up. This type of packaging tube doesn't look high-end enough. Therefore, a new type of packaging tube has been introduced that can be pressed down and pop out the bottom product. Document CN219593966U discloses a spring-loaded lipstick tube, including a first tube body, a middle tube body cap, a limiting mechanism, and a base. A guide block on the cap is installed in a guide groove of the first tube body. The cooperation between the two and the action of a spring between the cap and the base enables the axial movement of the cap. The middle tube body is nested inside the cap body. The inverted conical second limiting block, fitted on the middle section of the limiting mechanism, is larger than the conical first limiting block of the limiting mechanism. When the lipstick tube is pressed, because the second limiting block is larger than the first limiting block, the clamping mechanism disengages from the first limiting block and is limited to the second limiting block. When the lipstick tube is released, the middle tube body rises with the cap, popping out the first tube body for use. After use, the middle tube body is placed back into the lipstick tube and pressed down again to reset it.

[0003] When the aforementioned middle tube needs to be inserted into the lipstick tube, the second limiting block must first be allowed to fall freely back to its original position, i.e., the closed end of the lipstick tube should face down and the open end should be closed, so that the middle tube can be smoothly pressed down and stored in the lipstick tube. Therefore, its use is somewhat limited and inconvenient to operate. Utility Model Content

[0036] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. The following embodiments only illustrate the preferred implementation of this application. Although the description is relatively specific and detailed, it should not be construed as a limitation on the scope of patent protection.

[0037] See Figures 1-10 One embodiment of this application provides a cosmetic packaging tube for storing cosmetics such as lipstick, lip gloss, and mascara. It mainly includes components such as a tube body 100, a support component 200, a first elastic element 110, a first locking element 300, and a driving element 400.

[0038] The tube body 100 is generally tubular in structure, with an internal cavity for housing the supporting component 200. The tube body 100 has two ends, at least one of which is an open end 101. Figure 1-3 As shown, in one embodiment, the top of the tube is closed, and the bottom is open. For ease of manufacturing, as... Figure 4 As shown, in one embodiment, the tube body 100 includes an outer tube 102 and an inner tube 103. The outer tube 102 is open at both ends, and the inner tube 103 is closed at the top and open at the bottom. The inner tube 103 is assembled inside the outer tube 102 by adhesive bonding or interference fitting. The length of the inner tube 103 is less than the length of the outer tube 102, and it is located at the top of the outer tube 102, thereby closing the top of the outer tube 102.

[0039] like Figure 1-3 As shown, the support assembly 200 is used to hold cosmetics and is movably assembled in the storage cavity of the tube 100, allowing it to slide relative to the tube 100 along the axial direction of the tube 100. The support assembly 200 has two states, one of which is as shown... Figure 1 and Figure 2 As shown, the supporting component 200 is completely hidden inside the tube body 100, which is called the retracted state. The other state is as follows: Figure 3 As shown, the bottom of the support component 200 extends from the open end 101 into the tube body 100, which is referred to as the usage state. Figure 3 In use, the user can hold the tube body 100 with one hand and the bottom of the support component 200 with the other hand, and pull the support component 200 out of the tube body 100 to use it.

[0040] In some embodiments, the carrier component 200 includes a base 220 and a cover 210 that engage with each other. The base 220 is a component that carries cosmetics, and the cover 210 and the base 220 cooperate to confine the cosmetics within a closed cavity to prevent them from malfunctioning.

[0041] See Figure 2 and Figure 7 The inner wall of the cover 210 has a locking protrusion 212, which can be interference-fitted with the outer wall of the bottom product 220 to prevent separation. When it is necessary to separate the bottom product 220 and the cover 210, forces in opposite directions can be applied to them. Considering the uniform force distribution, there are multiple locking protrusions 212, which are evenly distributed circumferentially. In this embodiment, there are three locking protrusions 212.

[0042] To achieve simultaneous removal of the support component 200 from the tube 100 and separation of the bottom product 220 and the cover 210, in one embodiment, the cover 210 is restricted to movement within the tube 100. See also Figures 1-3 The tube body 100 is provided with a limiting part 120 inside. The limiting part 120 is a sleeve-type structure and is clamped and fixed between the limiting step on the inner wall of the outer tube 102 and the inner tube 103.

[0043] A protruding ring 211 is arranged on the outer periphery of the cover 210. The protruding ring 211 and the inner tube 103 are in clearance fit to ensure that the cover 210 can move axially without deflection. When the protruding ring 211 moves to the limiting part 120, since the wall thickness of the limiting part 120 is greater than the wall thickness of the inner tube 103, it can prevent the cover 210 from continuing to move towards the bottom of the tube 100.

[0044] The finished base 220 includes a base and a central core 250 fixed to the base. In this embodiment, the base includes an outer bottom 230 and an inner bottom 240 installed inside the outer bottom 230, and the central core 250 is fixedly connected to the inner bottom 240. Figures 1-3 The inner sole 240 is fixed to the top of the outer sole 230, and the outer surfaces of the top of the two are flush. The height of the inner sole 240 is much smaller than the height of the outer sole 230, so that there is installation space inside the outer sole 230.

[0045] In one embodiment, the middle core 250 includes a driving element, a guiding element, and a storage element. The inner wall of the driving element is provided with a spiral groove. The top of the driving element is inserted into the interior of the guiding element. An axial limiting mechanism is provided between the guiding element and the driving element, and the two can rotate relative to each other in the circumferential direction.

[0046] The storage element is used to hold the paste, extending partially into the interior of the drive element and engaging with the spiral groove, but its circumferential rotation is restricted by the guide element. When the drive element and the guide element rotate relative to each other, the drive element can drive the storage element to move axially, while the guide element can restrict the rotation of the storage element.

[0047] In some embodiments, the drive element is sleeved on the outside of the guide element, the guide element has a guide groove arranged along the axis, the storage element is placed inside the guide element, and the outer wall is provided with a connecting ear that extends through the guide groove into the drive element. The connecting ear cooperates with the spiral groove, so that when the drive element rotates relative to the guide element, it can drive the storage element to move along the axis.

[0048] In some embodiments, the central core 250 also includes decorative elements, in which the driving element, guiding element and storage element are all hidden, making the overall appearance more aesthetically pleasing.

[0049] like Figure 1-2 As shown, the drive member 400 is movably mounted on the bottom of the support assembly 200, is axially movable, and has a first position and a second position relative to each other. In one embodiment, the drive member 400 is axially movably mounted on the outer bottom 230, and includes an operating part 410 and a drive part 420. The operating part 410 is exposed, and the drive part 420 is inserted into the outer bottom 230. In use, pressing the operating part 410 can drive the entire drive member 400 to move axially.

[0050] The packaging tube also includes a second elastic element 430 that acts on the drive element 400 to reset it, see [link to documentation]. Figure 2 A first extension 423 is provided at the middle position of the top of the drive unit 420, and a second extension 241 is provided at the bottom of the inner bottom 240. A second elastic member 430 is sleeved between the two extensions. When the drive unit 400 is in the first position, the second elastic member 430 returns to its original position; when the drive unit 400 is in the second position, the second elastic member 430 is compressed.

[0051] like Figure 1 As shown, the first elastic element 110 acts directly or indirectly on the bearing assembly 200. When the bearing assembly 200 is in the retracted state, the first elastic element 110 is compressed, as shown... Figure 2-3 As shown, when the first locking member 300 is unlocked, the first elastic member 110 returns to its original state, driving the bearing assembly 200 to move from the storage state to the use state, that is, the bottom of the bearing assembly 200 can automatically pop out from the tube body 100.

[0052] In one embodiment, the first elastic member 110 is disposed between the cover 210 and the tube 100, and more specifically, between the cover 210 and the closed end of the inner tube 103. Figures 1-3 as well as Figure 7As shown, the top of the cover 210 has a narrowed portion 213, and the first elastic member 110 is sleeved on the narrowed portion 213, with its top end abutting against the closed end of the tube 100 and its bottom end abutting against the cover 210. The first elastic member 110 may be a spring.

[0053] like Figure 1-2 As shown, the first locking member 300 is used to lock the support assembly 200 in the stored state, preventing it from being dislodged from the tube body 100 due to external forces such as shaking. When the first locking member 300 is unlocked, the support assembly 200 can move from the stored state to the used state under the action of the first elastic member 110. During the process of the driving member 400 moving from the first position to the second position, it can drive the first locking member 300 to unlock.

[0054] like Figure 1-3 As shown in Figure 10, the first locking member 300 is connected to the driving member 400 and is movably disposed inside the outer bottom 230. The first locking member 300 includes a first locking portion 310 and a first elastic portion 320. The first locking portion 310 extends radially out of the outer bottom 230. Correspondingly, an opening 231 for the first locking member 300 to extend is arranged on the peripheral wall of the outer bottom 230. An annular groove 130 that mates with the first locking member 300 is formed on the inner wall of the tube body 100. The first elastic portion 320 extends obliquely between the first locking portion 310 and the driving member 400. The first elastic portion 320 has a driving inclined surface 330 that deforms to receive the release force. A first unlocking member that acts on the driving inclined surface 330 to unlock the first locking member 300 is provided on the outer bottom 230.

[0055] As the driving member 400 moves from the first position to the second position, it drives the first locking member 300 to move axially. The first unlocking member compresses the first elastic part 320, causing it to deform. The first locking part 310 moves radially and retracts to the outer bottom 230, disengaging from the annular groove 130 of the tube body 100, thus releasing the first locking member 300. When the driving member 400 moves from the second position to the first position, the first elastic part 320 returns to its original position, causing the first locking part to extend out of the outer bottom 230 again, allowing it to re-engage with the annular groove 130 of the tube body 100, achieving locking.

[0056] In one embodiment, there are two first locking members 300 arranged symmetrically.

[0057] To prevent the first locking element 300 from unlocking too quickly and affecting the movement of the carrier assembly 200, the packaging tube also includes a second locking element 350 where the locking drive element 400 is in the second position. See also Figure 10 The top of the drive unit 420 is hollow, with an axially extending strip-shaped notch 421. A second locking member 350 is formed between the two strip-shaped notches 421, and the second locking member 350 is an integral structure with the drive unit 420. See also Figures 1-3The second locking member 350 includes a second locking portion 360 and a second elastic portion 370 that drives the second locking portion 360 to reset.

[0058] The second locking member 350 is also located inside the outsole 230, and the second locking part 360 can lock with the outsole 230. See also Figure 3 and Figure 6b The inner wall of the outer bottom 230 is provided with an annular portion 232. Under the action of the release force, the second locking portion 360 is squeezed and passes through the annular portion 232. When the release force is removed, the bottom end of the second locking portion 360 abuts against the top end of the annular portion 232 to achieve locking.

[0059] In one embodiment, to avoid interference between the first locking member 300 and the second locking member 350, they are arranged in a staggered manner in the circumferential direction.

[0060] In one embodiment, the packaging tube includes a second unlocking member 235 that unlocks the second locking member 350. Figures 5-9 As shown, the outer sole 230 has several cuts 234 arranged around it to form a second unlocking member 235. When in use, the second unlocking member 235 is manually pressed. At this time, under the action of the second unlocking member 235, the second locking part 360 deforms inward and disengages from the annular part 232 to achieve unlocking.

[0061] After unlocking, the drive unit 400 is reset, that is, the drive unit 400 is in the first position, the first locking unit 300 is reset accordingly, and the first locking unit extends out of the opening 231.

[0062] When the load-bearing component 200 needs to be installed into the tube body 100, simply insert the bottom component 220 into the tube body 100 until the first locking part 310 engages with the annular groove 130 to achieve fixation.

[0063] For precise locking and unlocking, the drive component is 400° circumferentially limited, allowing movement only along the axial direction. See also Figures 8-9 A positioning rib 233 can be provided on the inner wall of the outer bottom 230, and a positioning groove 422 that cooperates with the positioning rib 233 is provided on the drive part 420. There are two positioning ribs 233 and two positioning grooves 422, which are arranged symmetrically, so that the drive part 400 is more stable during movement and will not shake.

[0064] Of course, in order to prevent the drive unit 420 from detaching from the outer bottom 230, a positioning part 440 is provided on the outer periphery of the drive unit 420, which is in clearance fit with the outer bottom 230, wherein the positioning groove 422 is provided in the positioning part 440.

[0065] The cosmetic packaging tube of this application allows the supporting component 200 to automatically pop out when the driving component 400 exposed on the base is pressed. Then, forces in opposite directions are applied to the tube body 100 and the supporting component 200, causing the bottom product 220 to separate from the cover body 210. The bottom product 220 can then be pulled out for use. After use, pressing the second unlocking component 235 resets the driving component 400, and the bottom product 220 is inserted into the tube body 100 until the first locking component 300 engages with the tube body 100. The operation is simple and convenient.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
